ORCHARD PARK, N.Y. (AP) — The Buffalo Bills have signed rookie offensive lineman Kyle Calloway, the second of the team's two seventh-round draft picks.

Listed at 6-foot-6, 323 pounds, Calloway had 37 starts in 39 games at Iowa and was a second-team Big 10 Conference selection in each of the past two seasons. He was selected 216th overall in the NFL draft in April.

The Bills also announced after a voluntary minicamp practice Tuesday that they waived defensive back Stephan Virgil, an undrafted rookie free agent out of Virginia Tech.
